Product Information

Tubular spring steel is used in the landing gear of some small aircraft due to its ability to absorb the impact of landing. Copper-base alloys are important spring materials because of their good electrical properties combined with their good resistance to corrosion. Although these materials are more expensive than the high-carbon and the alloy steels, they nevertheless are frequently used in electrical components and in sub-zero temperatures. The types of ends available for springs depend on the spring type since extension, compression, and torsion springs have different options regarding the types of ends they may have. Each spring has standard ends that easily conform to its type. Additionally, manufacturers offer customized ends to meet the needs of unique and unusual applications. Torsion spring end options – Torsion springs have a straight length of wire as their end, also referred to as a leg. The single type ending is due to the function of torsion springs, which is to deflect rotary force. Legs of torsion springs can differ in length, style, orientation, and angle, with the orientation referring to how the legs are positioned in relation to each other.

Music Wire, ASTM A228 (0.80-0.95 percent carbon): This is the most widely used of all spring materials for small springs operating at temperatures up to about 250°F. It is tough, has a high tensile strength, and can withstand high stresses under repeated loading. The material is readily available in round form in diameters ranging from 0.005 to 0.125 inch and in some larger sizes up to 3⁄16 inch. It is not available with high tensile strengths in square or rectangular sections. Music wire can be plated easily and is obtainable pretinned or preplated with cadmium, but plating after spring manufacture is usually preferred for maximum corrosion resistance. Springs can be classified according to the type and nature of the force acting on the spring. These can be further categorized by their geometry, form, and construction. The most common form of spring is a helical spring, which is made from a wire with a circular cross-section. Springs with special constructions exist for absorbing heavier loads or for fitting in mechanisms with small clearances. Helical Compression Springs:Copper is known for being a fairly soft and ductile metal, which means that it isn’t nearly so suitable as stainless steel is for bearing heavy loads. On the other hand, when the spring also needs to carry an electrical charge, beryllium copper springs might be able to provide the impact strength and anti-corrosion properties that are just right for the product you have in mind.

Compression spring end options – Compression springs are categorized according to their end type, which determines how they will be used. The four end types are closed and square, closed and ground, double closed, and open.

Hooke‘s law states that the force applied to the spring is directly proportional to its deflection, provided that it is within the elastic range. Each of these steel types must be carefully chosen, created and modelled into the spring of your choice, and each subtle adjustment to the make-up of the material must change how we approach the spring-making process, too. The most common form of spring is a helical spring, which is made from a wire with a circular cross-section. Extension springs are helical wound springs that are so closely coiled together to create initial tension in the coils. This initial tension creates resistance against the force applied to its ends for extension. The initial tension helps determine how closely and... Torsion Springs Chromium-Silicon Alloy (ASTM A401): These are available in cold-drawn or oil-tempered conditions. Chromium-silicon steel alloy can be heat treated to high hardness without losing much ductility. They are suitable in high impact loadings such as firearm recoil springs.

Ashfield Springs Ltd are the UK's leading compression spring, extension spring and torsion spring manufacturer and suppliers with a global reputation for excellence. We specialise in the manufacture of compression springs, and with nearly 40 years experience as an 'A' class supplier we supply many original equipment manufacturers in Europe, USA, India and China. Investment in Technology A spring is a flexible machine element that stores mechanical energy when subjected to tensile, compressive, bending, or torsional forces. A spring does not deflect through tension or compression. They change their dimension mainly due to torsion or shear. To further visualize, suppose the spring is unwound into a straight wire, typically with a round cross-section. The resulting free body diagram then becomes the cross-section of the wire with shearing forces acting on its periphery.

Customer Support and Manufacturing Capabilities

Since the spring is wound into a helix, the spring‘s curvature must be considered. The curvature effect is due to the shorter length of the inner side than the outer. The shear strain experienced by the inner and outer sides differs with the dimensions of the wire and torsional force. Moreover, the cross-section of the wire is subjected to direct shear. Direct shear is developed as the wire resists the applied load. More accurate models will use a term to account for the curvature of the wire and the direct shear stress, known as the Wahl correction factor. The resulting maximum shear stress (τ) is stated as, We understand how the make-up of your springs’ materials will benefit your end project: Copper Springs Monel K-500: Its composition is similar to Monel 400 but with the addition of small amounts of aluminum and titanium. The addition of aluminum and titanium allows it to be heat treatable through precipitation hardening.

Primarily used in electrical applications, copper springs can be vital to your final product. Titanium Springs These are steels with additional alloying elements such as chromium, vanadium, phosphorus, and silicon. Each element enhances different properties of steel, such as strength, hardness, and machinability. Barrel (Convex) and Barbell/Hourglass (Concave) Springs: These are helical springs with double cone geometries. They have the same advantages as that of conical springs. Closed and Square:The last coil of a closed and square compression spring is closed, making it possible to stand on end on a flat surface. The pitch of the end is reduced to form one dead coil. Cylindrical Springs: This is the most common type of spring. The pitch on these springs is equal. Since the pitch and coil diameters do not change along the length of the spring, the spring rate is constant.

Nickel-Base Spring Alloys with Constant Moduli of Elasticity

These are springs that are designed to deflect under compressive loads. They are the most commonly used and represent 80 to 90% of all springs manufactured. Compression springs geometries can be cylindrical, conical, convex, or concave. Variable Pitch, Cylindrical Spring: As the name suggests, these are cylindrical springs with varying pitch. This enables the spring to have a varying spring rate, which is also desirable for dynamic applications.
